Title: Semiconductor laser
Inventor: UNOSAWA HIROKIYO
IPC: H01S5/065
Filed: 1987-11-26
Abstract: PURPOSE:To easily obtain a semiconductor laser capable of making self- oscillation, by determining carrier concentrations of an active layer and of a clad layer such that diffusion length of carrier in the active layer is smaller than a half of a width of a second groove. CONSTITUTION:Carrier concentrations of an active layer 12 and of a second clad layer 13 are determined such that diffusion length of carrier in the active layer 12 is smaller than a half of a width W2 of a second groove. Since such diffusion length of carrier in the active layer 12 is controlled by the carrier concentration of the active layer 12, the carrier concentration of the second clad layer 13 and a width W1 of a first groove defined by a first block layer 14, this semiconductor laser is allowed to have gain distribution which is steep only in the part of the active layer 12 under the first groove. Further, if the diffusion length is larger than the width W2 of the second groove defined by the second block layer 16, the width of extension of laser light can be larger than the gain region. In this manner, a structure having equivalently a supersaturated absorbing body can be realized easily and self-oscillation can be caused more easily.

Title: Vibration suppressing device for tail cord of elevator
Inventor: KAGAMI MASAAKI
IPC: B66B7/06
Filed: 1988-11-29
Abstract: PURPOSE:To secure the superior vibrationproof operation by setting the radius of curvature in the vicinity of the neutral position of a guide locus to at least 1/20 of the total length of a tail cord and less than two times and reducing the restoration force due to the spring action in comparison with that due to the weight when the loaded weight at a swing supporting point is max. CONSTITUTION:Each rail surface 17, 18 is formed into an arcuate form projecting downward, and the relation L/20<r<2L is established between the radius (r) of curvature of the recessed part at the center and the total length L of a tail cord 3, and a restoration force is generated towards the center by the center of gravity acting onto the tail cord 3. The flexural rigidity of at each edge part 5, 6 of the tail cord, i.e., the restoration force generated by the spring action is less than the restoration force generated by the center of gravity. Since the restoration force of a floating suspension device is mainly determined according to the radius of curvature of the swing locus and the suspension weight, the restoration force is automatically increased and decreased according to the variation of the suspension load weight distribution, and even if the suspension load weight distribution of the floating suspension device changes by the rise of the cage, a proper restoration force can be obtained at all times.

Title: Precise direct advance actuator
Inventor: KOSUGI MASAO
IPC: H02N2/00
Filed: 1989-11-20
Abstract: PURPOSE:To achieve positioning accuracy shorter than 1mum and a stroke longer than 1mm by providing a direct advance means for limiting rotation and performing only linear motion and a screw and nut coupling means for converting the rotation into linear motion. CONSTITUTION:Frictional face 7 of a rotor 6 receives traveling wave from a stator 1 thus causing rotation of the rotor 6. The rotor 6 is secured through a screw 9 to a female side ball screw(nut) 10. Upon operation of an ultrasonic motor under this state, nut 10 side of the ball screw rotates but since the rotation is limited at the shaft side, it causes axial motion. When angular positioning resolution of the ultrasonic motor is set at 15sec and the lead of the ball screw 10 is set at 2mm, a very high positioning resolution is achieved where axial feeding pitch is 0.023mum and 0,011mum for lead of 1mm.
